A housing case body comprises a housing member housing the disc holder and a mounting member with which the engagement portion of the disc holder housed by the housing member engages. A disc housing case combines the disc holder and the housing case body.

The present application is a continuation application of U.S. patentapplication Ser. No. 07/435,042, filed Nov. 9, 1989, and now abandoned.

BACKGROUND OF THE INVENTION

The present invention relates to a disc holder for housing and carryingan information-recording disc such as compact disc (CD) and the like,and more particularly to a housing case body for housing disc holders,and a disc housing case which combines the disc holders and the housingcase body.

So as to protect it from dust and the like, the compact disc isgenerally stored in a disc housing case. FIG. 1A and FIG. 1B illustrateone example of this type of disc housing case which has beenconventionally used. The disc housing case 1 comprises a case body 2 anda cover 3 made of resin. A central hole 13a of a disc 13 is clamped by aclamp portion 2a of the case body 2. And closing the cover, the dischousing case holds and protects the disc 13 in an approximately airtightstate.

However, there has been a recent spread of portable players andautomobile players designed for compact discs and this has led to anincrease in the number of occasions when a number of compact discs arecarried. When a large number of compact discs are carried, the combinedvolume of the disc housing case 1 shown in FIG. 1A and FIG. 1B becomeslarge. Because of this, a disc housing case having a structure whereinit is provided with a plural number of storage trays having pocketportions housing compact discs is proposed so that a large number ofcompact discs can be carried conveniently.

As has been described above, conventional disc housing cases (refer toFIG. 1A and FIG. 1B) include those that are designed mainly for theobjective of storage and some that are designed for carrying.Accordingly, when stored compact discs are to be carried, it isnecessary to take the appropriate discs out of their disc housing casessuited to storage and transfer them to a disc housing case suitable forcarrying the selected compact discs. In addition, when the compact discsthat have been carried are to be stored again, it is necessary to takethe discs out of the disc housing case suitable for carrying, andtransfer the carried discs into the disc housing cases suitable forstorage.

In this way, conventional disc housing cases involve the task oftransferring the compact discs from one case to another when storedcompact discs are to be carried, or when carried compact discs are to bestored. When compact discs are repeatedly stored and carried, it isnecessary to take care with respect to the attachment of dust and otherforeign matter and thus the task of transferring the compact discsbecomes laborious.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 2 is a perspective view indicating a first embodiment of the dischousing case according to the present invention.

The disc housing case 6 comprises a disc holder 7 and a housing casebody 8. The disc holder 7 includes a base member 9 formed of a thinsheet of resin, and a sheet member 10 formed of resin. With theexception of one of the edges of this sheet member 10, the edge portionof this sheet member 10 is affixed by thermal adhesion or the like tothe base member 9 so as to form a pocket 11. The sheet member 10 and thebase member 9 are adhered so as to form a circular line along the edgeof the join, so that the edge of a disc 13 housed in the pocket 11 is incontact along its edge with this join and so that the disc 13 issecurely housed in the pocket 11 without deformation of the disc 13 inthe pocket 11 occurring. The base member 9 is rectangular in shape andhas a structure whereby the edge on one side 9a can be arbitrarily bentin the direction of the arrow A. The edge on one side 9a of this basemember 9 has two holes 12a and 12b formed along this one side of thebase member 9.

When the disc 13 is housed in the pocket 11 formed in the disc holder 7,the greater portion of the disc 13 is covered by the base member 9 andthe sheet member 10. By this, the adhesion of dust or grime to the disc13 is prevented.

The housing case body 8 includes a rectangular-shaped plate 8a, on bothsides of which are formed flange portions 8b and 8c, and a flangeportion 8c formed on the bottom edge.

In a housing case body 8 having the structure described above, thesurface of the plate 8a is surrounded by the flange portions 8a, 8b and8c to form a housing portion 14. The disc holder 7 is housed in thishousing portion 14. Guide grooves 15a and 15b are formed on the insideof each of the flange portions 8b and 8c and on the inside of the flangeportion 8d is formed a stop groove 16. The flange portions 8b and 8c areformed in a C-shape in section by the guide grooves 15a and 15b. Theguide grooves 15a and 15b are formed so that they engage with the outerperipheral portion 7a and 7b of the disc holder 7.

The disc holder 7 is housed in the housing case body 8 in the followingmanner.

First of all, as is indicated by the arrow in the diagram, the leadingend portion of the side edges 7a and 7b is inserted into the guidegrooves 15a and 15b from the side of the open end that does not have aflange portion formed in the plate 8a, and the side edges 7a and 7b areguided along the guide grooves 15a and 15b so as to slide. Then, theleading edge portion (the one edge portion 9a) of the disc holder 7engages with the stop groove 16 of the flange portion 8d. In thisstatus, the disc holder 7 is housed in the housing portion 14 of thehousing case body 8 and the outer peripheral portion of the disc holder7 is guided and held by the guide grooves 15a and 15b and the stopgroove 16. Accordingly, the disc holder 7 is securely housed in thehousing case body 8.

The disc holder 7 and the housing case body 8 form the one case and sothe disc 13 housed in the disc holder 7 is securely stored.

The disc housing case 6 comprising the disc holder 7 and housing casebody 8 described above has a structure that is particularly suited tohousing a single disc 13. However, if each of the flanges of the housingcase body 8 are formed higher and the number of grooves increased, thenit is possible to house several disc holders 7 (i.e. several discs 13).

FIG. 3A, FIG. 3B, FIG. 4 and FIG. 5 are perspective views indicating adisc housing case 17 according to a second embodiment of the presentinvention.

In particular, FIG. 3A and FIG. 3B indicated the completed status of thedisc housing case 17 and FIG. 4 indicates the assembly status of thedisc housing case 17.

In this embodiment, the disc holder 7 that directly houses the disc 13has the same structure as that described for the first embodimentaccording to the present invention and as has been described previously(refer to FIG. 2). This disc housing case 17 can house a plural numberof disc holder 7 and therefore has a structure whereby a plural numberof discs 13 can be carried at the same time.

In this case, the housing case body housing the disc holder 7 includes arectangularly-shaped upper plate cover 19, a lower plate cover 20 havingthe same shape, and linkage pins 18 and 18 linking them.

The linkage pins 18 and 18 have the structure indicated in FIG. 5. Thisis to say that the linkage pins 18 and 18 comprise a male thread portion18a and a female thread portion 18b and each of the male thread portion18a and the female thread portion 18b has a pin portion 18a-1 and 18b-1.By this, when each of the male thread portions 18a and female threadportions 18b are in the threaded status, the head of each screw isseparated by a distance corresponding to the lengths of the pin portions18a-1 and 18b-1, and thereby form the linkage pins 18 and 18.

The upper plate cover 19 and the lower plate cover 20 are formed ofresin sheet and so as indicated in FIG. 4, pairs of holes 19a and 19b,and 20a and 20b are formed at positions in opposite corners. The lengthL₁ of one side of this upper plate cover 19 and lower plate cover 20 isset to be equal to the length l₁ of one side of the disc holder 7 (i.e.L₁ =l₁) and the length L₂ of the other sides of the upper plate cover 19and the lower plate cover 20 are set so as to be longer than the lengthl₂ of the other sides corresponding to the disc holder 7 (i.e. L₂ >l₂).

A plural number of disc holders 7 can be housed in the space between theupper plate cover 19 and the lower plate cover 20. More specifically, asis shown in FIG. 4, the disc holders 7 in the stacked state aresandwiched between the upper plate cover 19 and the lower plate cover20. The length of one side L₁ of the upper plate cover 19 and the lowerplate cover 20 is equal to the length l₁ of one side of the disc holder7 and so the hole 12a in each of the disc holders 7 is in alignment withthe holes 19a and 20a in the upper plate cover 19 and the lower platecover 20. Then the male thread portion 18a and the female thread portion18b are passed through the holes 19a, 12a and 20a and screwed together.The upper plate cover 19 and the lower plate cover 20 are linked at oneend and a plural number of disc holders 7 can be mounted to the linkagepin 18. This linkage pin 18 functions as a mounting member for the discholders 7. In addition, the length L₂ of the other sides of the upperplate cover 19 and the lower plate cover 20 are longer than the lengthsl₂ of the other sides of the disc holder 7 and so the male threadportion 18a and female thread portion 18b are passed through the otherholes 19b and 20 b of the upper plate cover 19 and the lower plate cover20 and threaded to each other so as to link the upper plate cover 19 andthe lower plate cover 20 at the appropriate end portions.

As has been described above, the assembly of the disc housing case 17having the upper plate cover 19, the lower plate cover 20 and the discholder 7 involves only passing the linkage pins 18 and 18 through thehole 12a formed in the disc holder 7, the pairs of holes 19a and 19b,and 20a and 20b formed in the upper plate cover 19 and the lower platecover 20. The assembly is therefore simple.

In addition, transferring discs 13 stored in the disc housing case 6shown in FIG. 2 to the disc housing case 17 is performed by transferringthe disc holder 7 housing the disc 13. Accordingly, when discs 13 aretransferred from disc housing case 6 suited to the storage of compactdiscs to a disc housing case 17 suited to the carrying of compact discs,it is not necessary to remove the discs from the disc housing cases.Therefore, the task of transferring the discs is facilitated and theadhesion of dust and the like to the compact discs is prevented.

FIG. 3A shows the status where a plural number of compact discs ishoused in the space between the upper plate cover 19 and the lower platecover 20. In this status, taking out the discs 13 is performed as shownin FIG. 3B by pivoting the disc holders 7 housing the necessary discs 13about the center of the linkage pin 18, so that disc holder 7 is exposedfrom the space between the upper plate cover 19 and the lower platecover 20.

Moreover, in this second embodiment according to the present invention,only a single hole need be formed in the disc housing case 17 for thelinkage pin 18 to pass.

FIG. 6 shows an alternative embodiment of the disc housing case 17indicated in FIG. 3A through FIG. 5.

The disc housing case 22 indicated in FIG. 6A and FIG. 6B has astructure whereby a plural number of disc holders 7 are housed in a casethat includes cover plates 23 and 24 opposing each other by apredetermined distance. The case is provided with a lid 25. Each of thedisc holders 7 is held within the case by a pin (not shown in thefigure) provided in the case, being inserted into a 30 hole 12a in thesame manner as indicated in FIG. 3A and FIG. 3B. The lid 25 can pivotaround the center of the open end of the case and the lid 25 can bepivoted to open and close the case. When the lid 25 is opened, the discholders 7 can be pivoted about the pin and brought out of the case, andthe discs 13 can be housed in or taken out from the corresponding discholders 7.

In this alternative embodiment, a lid 25 is provided on a case includingcovers 23 and 24 so that the intrusion of dust into the disc housingcases 22 can be definitely prevented. When the lid 25 is closed, a hookportion (not indicated in the figures) formed at the end of the lid 25engages with a stopper 27 on the case side so that the lid 25 is locked.By this, the lid 25 does not open easily when the disc housing case isbeing carried, and the disc holders 7 are definitely prevented fromfalling out.

Moreover, the disc housing case 22 is provided with a belt 26 tofacilitate the carrying of the disc housing case 22 and make it easierto use. FIG. 7A and FIG. 7B are perspective views indicating a thirdembodiment of a disc housing case 21 according to the present invention.In this embodiment, the disc holder 7 directly housing the disc 13 has astructure similar to that which has been explained previously for thefirst embodiment and the second embodiment (refer to FIG. 2). The dischousing case 21 is the same as for the first embodiment and the secondembodiment in that it is structured so that a plural number of discholders 7 are sandwiched between an upper plate cover 35 and a lowerplate cover 36.

In particular, the upper plate cover 35 has one edge portion that can bearbitrarily bent as is the disc holder 7, and is formed with two holesat positions the same as the holes two holes 12a and 12b provided in thedisc holder 7. In addition, the one side portion of the lower platecover 36 is provided with two holes in the same manner. Thus, A pluralnumber of disc holders 7 are sandwiched between the upper plate cover 35and the lower plate cover 36, the two linkage pins 18 and 18 are passedthrough each of the holes and the upper plate cover 35 and the lowerplate cover 36 and the disc holder 7 form a single unit. In this case,the two linkage pins 18 and 18 function as mounting members for the discholders 17.

In a disc housing case 21 having the structure as described above, theupper plate cover 35 and one side of each of the disc holders 7 are ableto bend arbitrarily so that the disc holders 7 can be turned over likethe pages of a book so that the disc holders 7 can be looked at insequence from the upper plate cover 35. Thus, the discs 13 are eithertaken out from the disc holders 7 that have been turned over, or arestored to the appropriate disc holder 7. Accordingly, the disc housingcase 21 facilitates the housing of discs 13 into the disc housing case21 and also facilitates their being taken out from the disc housing case21.

FIG. 8 indicates an alternative embodiment of the disc housing case 21indicated in FIG. 7A and FIG. 7B above.

The disc housing case 28 indicated in FIG. 8 includes a lid 29b and areceiving portion 29a forming the housing case body, and one side of thereceiving portion 29a is (hinge) engaged to the lid 29b so as to bearbitrarily pivotable with respect to it. In the receiving portion 29a,there are mounting pins 32a and 32b provided close to the engagementwith the lid. These mounting pins 32a and 32b have axial portions withdiameters smaller than the diameters of the tip end portions. Thereceiving portion 29a and the lid 29b forming the housing case body asdescribed above are formed of a hard resin. In other words, the housingcase body is a hard case. In addition, the disc holder 30 that isanother element that configures this disc housing case 28 issubstantially similar to it indicated in FIG. 2. But the engagementportion that engages the mounting pins 32a and 32b provided on thereceiving portion 29a described above communicates with the holes andthe exterior of the base member. This is to say that two engagingconcave portions 31a and 31b form a substantially U-shape portion in oneside of the disc holder 30. A space between these two engaging concaveportions 31a and 31b has the same span as that between two mounting pins32a and 32b inside the receiving portion 29a. Therefore, a plural numberof disc holders 30 in engagement with the mounting pins 32a and 32binside the receiving portion 29a are stacked in sequence.

The disc housing case 28 with an embodiment such as this enables discholders 30 to be housed in and taken out from the disc housing case 28without the necessity to remove the mounting pins 32a and 32b frominside the receiving portion 29a, and therefore facilitates the housingand taking out of the disc holders 30. The disc holders 30 inside thereceiving portion 29a are able to be turned in much the same way aspages in a book, as in the case for FIG. 7A and FIG. 7B. The necessarydisc holder can therefore be selected.

In addition, in the state where the lid 29b is closed, it is notpossible for dust to enter into the receiving portion 29a and inaddition, since the housing case body is a hard case, the discs 13 arealso protected from impact forces applied from outside.

FIG. 9A through FIG. 9C are perspective views indicating anotherembodiment of a disc holder.

This disc holder 40 includes a thin rectangular-shaped base member 41formed from the same resin as used for the base member of FIG. 2, and asheet member 42 formed of the same resin. The sheet member 42 and thebase member 41 are joined by thermal adhesion so that there is anopening on the corner opposite the base member 41. The line of thisadhesion forms an arc 42a in the center of the space formed by the twolines 42b and 42c of both sides. The arc 42a formed by the adhesion lineis in agreement with the outer circumference of a compact disc to behoused, and the base member 41 and the sheet member 42 together form apocket 45. The opening side of the pocket 45 has a concave engagingportion 46 is configured from a hole 46a and a communicating portion 46bthat communicates with this hole 46a and the outside of the base member41. Thus, the communicating portion 46b has the opening width W₂ to thehole 46a less than the opening width W₁ to the outside of the basemember 41. In addition, as shown in FIG. 9C, the disc holder 40 has asheet member 42 on the opening side of the pocket and which can bepeeled back. An insertion hole 47 for a finger in the pocket 45 of thebase member 41. When a finger is inserted through the insertion hole 47from the underside of the base member 41, the disc 13 inside the pocket45 can be lifted up, so that the taking out of the disc 13 from thepocket 45 is facilitated.

The disc holder 7 and the disc holders 30 indicated in FIG. 2 and FIG. 8respectively, can be either flexible or not flexible, but disc holder 40shown in FIG. 9A through FIG. 9C is of a flexible structure.

FIG. 10A is an exploded perspective view indicating the configuration ofthe entire disc housing case.

The housing case body housing the disc holders 40 includes an outer case50 and an inner case 60.

The outer case 50 has a upper plate 51 and a lower plate 52 and a sidewalls 53 and 54 formed so as to hold and separate the upper plate 51 andthe lower plate 52 at a predetermined distance. Moreover, the side wall54 is not indicated in the figure. The side walls 53 and 54 respectivelyengage with the corners of the upper plate 51 and the lower plate 52 andas a result of this, the upper plate 51 has a structure whereby each ofthe side walls 53 and 54 open on opposite sides. At the corners of theupper plate 51 and the lower plate 52 at the ends of the non-engagementend of the side wall 54, are formed stop members 55 and 56 provided withstop holes 55a and 56a.

The inner case 60 has a base plate 61 and two side walls 62 and 63formed on two sides of the base plate 61. Each of these side walls 62and 63 are engaged by a corner of the base plate 61. As a result ofthis, the inner case 60 has a structure whereby the walls opposite thetwo side walls 62 and 63 are open. A stopper member 64 and a fan-shapedplate 65 are formed at the top portion of the non-engagement end of theside wall 63. The stopper member 64 is provided with a stopper hole 64a.In addition, a corner of the base plate 61 ha a stopper member formed inthe same manner opposing the upper stopper member 64. (This is not seenin the figure.) This stopper member formed at the lower portion also hasthe a stopper member formed at the lower portion also has stopper member64 of the upper portion. An opposite side of the edge forming the sidewall 62 of the base plate 61 is formed with a slider groove 67 and theunderside of the stopper member 64 is formed with a slider groove havinga structure that is similar with respect the slider groove 67 of thebase plate 61. (This is not seen in the figure.)

A mounting pin 68 is provided in the inner case 60. This mounting pin 68comprises a shaft portion 68a, a upper slider 69 provided at an upperend of the shaft portion 68a and a lower slider 70 provided at a lowerend of the shaft portion 68a. The upper slider 69 and the lower slider70 both have cutout portions 69a and 70a formed in them respectively.Thus, the upper slider 69 engages with the upper slider groove formed onthe inner case 60 and the lower slider 70 engages with the lower slidergroove 67 formed on the inner case 60, and so as to be freely slidable.

Each of the stopper members 64 of the inner case 60 are sandwichedbetween each of the stop members 55 and 56 of the outer case 50 and theinner case 60 is inserted into the outer case 50. Then, a stop pin 72aformed in the engagement member 72 is inserted in the stop hole 56a ofthe stop member of the inner case 60. And a stop pin (not shown in thefigure) formed on the other engagement member 71 is inserted in the stophole 55a of the stop member 55 of the outer case 50 and the stop hole64a of the stop member 64 of the inner case 60. These engagement members71 and 72 form a single unit with the outer case 50 and the inner case60. In this state, the upper and lower slides 69 and 70 of the mountingpin 68 inside the inner case 60 do not contact the stop pin of the upperand lower engagement members 71 and 72 because of the cutout portions69a and 70a. The inner case 60 which forms a single unit with the outercase 50 is therefore pivotable rotatable around the center of the stoppins 71a and 72a of the upper and lower engagement members 71 and 72.When the inner case 60 is pivoted around the center of the stop pins 71aand 72a of the upper and lower engagement members 71 and 72 and ishoused inside the outer case 50, the side walls 62 and 63 of the innercase 60 close the opening portion of the outer case 50 as shown in FIG.11A, and a housing case body that is airtight overall is formed.Moreover, a hook 62a is formed at the end portion of the side wall 62 ofthe inner case 60 so that when the inner case 60 is closed, this hook62a engages with a stopper portion 50a on the side of the outer case 50.Because of this, there is no danger that the inner case 60 willnaturally open when the disc housing case is carried.

Furthermore, when the inner case 60 pivots around the center of each ofthe engagement members 71 and 72 to come out of the outer case 50, thedisc holders 40 inside the housing case body are exposed as is shown inFIG. 11B. As shown in FIG. 10, the concave engaging portion 46 of eachof the disc holders 40 engages with the shaft portion 68a of themounting pin 68. And the disc holders 40 are held inside the housingcase body. The status of this engaging portion becomes as shown in FIG.11C and the disc holder 40 is lightly engaged with respect to the shaftportion 68a of the mounting pin 68 so that it is freely movable in thedirections of the arrow A. Then, the mounting pin 68 that is inengagement with the disc holder 40 can slide along the slide groove 67inside the inner case 60 and in the direction the arrow B in FIG. 11C sothat the disc holder 40 is able to be taken from and inserted into thehousing case body as is shown by the arrow in FIG. 11B. When the discholder 40 is pulled out, a disc 13 can be housed in or taken out fromthe housing case. When the disc holder 40 is in the state where it hasbeen pulled out of the housing case, it is possible to house a disc 13in the disc holder 40 and to take a disc 13 out from the disc holder 40and so these tasks are facilitated.

The communicating portion 46b of the concave engaging portion 46 formedin the disc holder 40 has a portion of narrow width as is indicated inFIG. 9B. This width is narrower than the width of the shaft portion 68bof the mounting pin 68 inside the housing case body. And the discholders 40 are flexible. Therefore, when the disc holder 40 is pulledout from the housing case body by a strength smaller than a strengththat causes a deformation in the vicinity of the concave engagingportion 46 of the disc holder 40, the concave engaging portion 46 is notdetached from the shaft portion 68a of the mounting pin 68 with ease. Onthe other hand, a strength applied when the disc holder 40 is pulled orpushed, causes a deformation in the vicinity of the concave engagingportion 46 of the disc holder 40 is deformed causes the disc holder 40to attach and remove with respect to the mounting pin 68.

Moreover, as is indicated in FIG. 11A, this disc housing case has acatch 75 formed in the engaging portions of the outer housing case has acatch 75 formed in the engaging portions of the outer case 50 and innercase 60 and this catch 75 has a belt 80 attached to it to facilitate thecarrying of the disc housing case.

The present invention is not limited to the aforementioned embodiments,and variations and modifications may be made without departing from thescope of the invention.
